2014 PORSCHE 911 tyre pressure

Wheels.
The 911 Carrera models are equipped
with 19-inch Carrera wheels as standard.
These are light weight alloys featuring a
classic sport y design. Tyre sizes are
235/40 ZR 19 and 285/35 ZR 19 at the
front and rear, respectively. All-wheel-
drive models are fit ted with even wider
295/35 ZR 19 t yres at the rear.The S models are equipped with light-
alloy 20 -inch Carrera
S wheels as
standard. The visual effect is sport y and
dynamic. The t yres are slightly wider to
cope with the increased power output of
these models: 245/35 ZR 20 at the
front, 295/30 ZR 20 at the rear. All-
wheel-drive models have 305/30 ZR 20
t yres at the rear.
The large t yre size improves both ride
comfort and track performance. Rolling
resistance, dry braking distances and t yre
weight are all comparatively low, thereby
helping to reduce fuel consumption.
A selection of 20 -inch wheels is available
in our range of options.
Tyre Pressure Monitoring (TPM).
Integrated as standard, Tyre Pressure
Monitoring (TPM) sends warnings to the
on-board computer’s display screen in
the event of low t yre pressure or a
gradual or sudden loss of pressure. The
individual pressures in all four t yres can
be displayed in the instrument cluster.
Porsche Stability Management (PSM).
As standard, the 911 Carrera models are
equipped with enhanced Porsche Stability
Management (PSM), which maintains sta -
bilit y even at the limits of dynamic driving
performance. Sensors continuously moni -
tor the direction, speed, yaw velocit y and
lateral acceleration of the car. Using this
information, PSM is able to calculate the actual direction of travel at any given
moment. If the car begins to oversteer or
understeer, PSM applies selective braking
on individual wheels to restore stabilit y.
Under acceleration on wet or low-grip
road surfaces, PSM improves traction
using the automatic brake diffe
rential
(ABD) and anti -slip regulation (ASR).
When the SPORT PLUS mode of the
optional Sport Chrono Package is selected,
the PSM threshold is raised to allow a
sportier driving style.
For an even more dynamic experience,
you always have the option to deactivate
PSM. It is automatically reactivated,
for your safet y, only if you brake harder
and either of the front wheels (in SPORT
PLUS mode, both of the front wheels) requires ABS assistance. ABS and ABD,
however, remain active at all times.
PSM therefore offers a high level of

driving stability and safety combined
with extraordinary agilit y. It ’s an
apparent contradiction in terms, but an
intrinsic part of the Porsche identit y.

Engineering that takes you forward:
optional Porsche Communication
Management (PCM) with navigation
module and a high-resolution 7-inch
colour touchscreen. PCM is your control
centre for audio, navigation and
communication functions.Instruments.
Sport y not kitsch, practical not fanciful.
The five round instruments have one
purpose above all: to provide information.
They do so efficiently and accurately.
Their st yling is t ypically Porsche with the
rev counter exactly where you would
expect it to be: in the middle.
Another element of the Porsche identit y
is sound. Fit ted as standard, the
CDR audio system with 7-inch colour
touchscreen and the Sound Package Plus
offer outstanding performance with a
total output of 235 wat ts. Available as an
option is the BOSE
® Surround Sound
System with a total output of 445 wat ts.
In short, it delivers powerful audio playback combined with an impressive
spatial sound.

No system promises such high standards
in the 911, and fulfils them, as the
optional High-End Surround Sound
System from Burmester®, the bespoke
manufacturer based in Berlin and one of
the most respected premium audio
manufacturers worldwide. With a total output of 821
wat ts, it ensures an
incredible audio experience.
Our patented integral subwoofer enhances
the bass performance of both optional
sound systems and also saves weight.
Typically Porsche.
Ergonomics, st yle and sound. Sports car
technology, intelligently combined. The instrument cluster with a high-
resolution 4.6-inch TFT colour screen
provides you with a continuous stream of
data from the on-board computer, such
as trip mileage, journey time or average
fuel consumption. It also displays the
navigation system map, delivers various
warnings, including alerts from the Tyre
Pressure Monitoring (TPM) system and,
in 911 Carrera 4 models, tells you
the current front /rear axle torque
distribution. You can also use it to
personalise various in-car settings.
